Abstract
According to one embodiment of the present invention, a cast alloy material is provided. The cast alloy material includes a matrix metal and an alloy element, wherein oxide particles in a nanometer scale are decomposed in the matrix metal, so that a new phase including a metal element that is a component of the oxide particles and the alloy element forms a band or network structure, wherein the metal element and the alloy element have a relationship of a negative heat of mixing, and wherein oxygen atoms formed by decomposition of the oxide particles are dispersed in the matrix metal and do not form an oxide with the matrix metal.
